Technical Information Design Articles

Compression Spring Tech

Compression springs are also known as coil springs. They are open wound linear springs because they have the same amount of pitch between each one of the coils. Learn about their dimensions, specifications, and how they work.

Extension Spring Tech

Extension springs are also known as tension springs. They are close wound linear springs because there is initial tension keeping the coils together as to be pulled apart. Learn about their dimensions and how they work.

Torsional Spring Tech

Torsional springs are also known as torsion springs. They are close wound rotational springs with legs on the ends because they deflect radially under torque. Learn about their dimensions, specifications, and how they work.

Conical Spring Tech

Conical springs are also known as tapered springs. They are non-linear compression springs for they are open wound but have variable coil diameters. Learn about their dimensions, specifications, and how they work.

Spring Rate

Spring rate is the proportional amount of force per one unit of distance traveled. This is what makes compression and extension springs linear. Learn about the formulas, calculations, and how spring rate works.

Spring Design

Spring design is very extensive since there are several subjects to learn about per spring type. Below you can find general design information for the three main spring types; such as formulas and explanations on how everything works.

For the advanced search, you must select “Search More Fields”. Here you can enter:

Once you’ve entered your spring’s specifications, click “Search”.

After you have clicked “Search” on the Spring Finder, you will be directed to a page of results. The number of results you will get depends on the dimensions and ranges you entered. You can choose to view from fourteen to seventy results in one page and you can choose whether to view them in a table/list or side by side as products in grid format. Besides choosing the quantity of results you want to view, you can also organize them based on the specification of your choosing.

The following are the specifications you can select to organize your search:

Product Name

Price

After sorting the products in the order of your choosing, you can start looking through the list to decide which spring will work best. You can find the spring based on the maximum load or the maximum deflection. When you find the spring that meets your load and travel requirements, you can then check whether the spring rate meets your working loads. Furthermore, you can check pricing at different quantities by clicking on the Quick View icon.

If you still need help deciding select your springs and “Add to Compare” by clicking on the icon of two circles joined together on each product. This is to be able to compare them side by side in a more efficient manner. To enter the Compare Products page, find the link at the top of the page. Then, just quickly add them to your cart to complete your order. If you need further assistance finding your springs, you may contact our team of experts to help you out. Our engineers can help answer your questions and assist you in finding the correct spring for your application.

Extension Spring Finder

Find and buy stock extension springs in two easy steps using Spring Finder. This simple tool makes finding the stock tension spring you need a fast and productive task. Search through over 4,000 designs off the shelf.

The following simple steps will get you started:

When searching for a stock extension spring, you base your search on its parameters and tolerances. We do have thousands of springs in stock but, most likely, you will find springs similar to yours, not exact replicas. Spring Finder will allow you to search for your springs in both english and metric units. Initially, it gives you three parameters to search your spring by but gives you the opportunity to expand it into a more advanced search where you have more parameters to choose from.

In the basic search, you can enter:

outer diameter

length inside hooks

spring rate

Next to each dimension, you will see two input boxes where you can enter your max. and min. tolerances for that specific parameter.

To access the parameters in the advanced search, click on “Search More Fields” where the following dimensions will be available:

load

deflection (travel required)

initial tension

wire diameter

material type

The fields are not mandatory so you can choose whatever dimension you feel needed and click “Search” once you have done so.

After clicking “Search” on the Finder, you will be directed to a page of results. These results are displayed in a table/list as default but you can select to view them in a grid format where they will be shown side to side. The amount of results you get will depend on how many dimensions you entered and how tight or loose the tolerances are. Based on how many results you generate, you can also choose to show from fourteen to seventy products per page.

These are the specifications you can organize your extension springs by:

Part Number

Price

Outer Diameter

Length Inside Hooks

Max. Load

Max. Deflection (Max. Travel Required)

Initial Tension

Wire Diameter

After you have figured out how you want to display the results of your Spring Finder search, you can begin finding potential products based on the suggested max load and deflection/travel, as well as the spring rate. Select all of your potential springs and “Add to Compare”. Scroll to the top of the page once you have done so and click on “Compare Products” where they will be displayed side to side. Check out pricing at different quantities by clicking on “Quick View” or click on the part number to be directed to the product details page.

Stock Wire Spring Types

Definition: Springs made up from wire that is radially wound in a circular shape to form adjoining coils.

StockSpringsCatalog.com by Acxess Spring is a spring company which specializes in manufacturing stock and custom wire springs. The types of stock wire springs we offer in our online wire spring catalog are wire compression springs, wire extension springs, wire torsion springs, and wire conical springs. Below you will be able to see these types of springs.

Compression springs are used to compress (shrink) when a load is applied but to return to its original position once that load has been removed. They are the most common type of wire springs and you can find several designs in our stock compression spring catalog although you may also request a custom quote in case you weren’t able to find what you need in stock. Calculate a wire compression spring design using our compression spring calculator where you will also be provided with similar wire compression springs in stock as well as a custom quote for that specific wire compression spring design.

Torsion springs are used to exert a radial/rotational force. The wounded coils contract during deflection since the coils are technically being twisted further more. Torsion springs can be found in stock spring online stores such as StockSpringsCatalog.com. If your torsion spring is required to have bends on the legs, you may also request a custom quote. Calculate a wire torsion spring design using our torsion spring calculator where you will also be provided with similar wire torsion springs in stock as well as a custom quote for that specific wire torsion spring design.

Extension springs are used to extend (become longer) when a load is applied and to shrink back to its original length once the load has been removed. You can find stock extension springs in various sizes using our extension spring finder to automatically search through our stock extension spring catalog. Calculate a wire extension spring design using our extension spring calculator where you will also be provided with similar wire tension springs in stock as well as a custom quote for that specific wire tension spring design based on different quantity lots from 25 pieces up to 25,000 pieces.

Conical springs are basically compression springs with modified coil diameters that give it a cone/tapered shape. These spring work the same way wire compression springs do except their spring rate is non-linear and they are able to perform a telescope effect when being compressed which provides stability and shortens the solid height. Find stock conical wire springs using our wire cone spring finder which will automatically search for stock cone wire springs within our conical springs catalog.
